I am an astrophysicist. My main interest is to understand how star forms from the diffuse medium, which we call the molecular cloud. Stars are fundamental building blocks of the universe, and one of their key characteristics is their mass. The process though which stars acquire their mass involves multiple physical mechanisms such as gravity, thermal pressure, turbulence, magnetic field, radiation, and cosmic rays. I perform numerical simulations of stellar cluster formation and try to understand how mass is distributed into individual stars. I also do detailed simulations of collapse of prestellar cores to understand the formation of individual stars.
